Fish are raised together with, the ecological cultivation method of loach in a kind of rice field
Technical field
The present invention relates to aquaculture field, particularly relate to a kind of rice field and raise together with fish, the ecological cultivation method of loach.
Background technology
At present, all to face space resources in short supply for China's agricultural Fisheries Development, the deterioration of the ecological environment, drug abuse, problem of low quality, plantation and fanning economics not high, can not transfer farmer concepts.If plant husbandry and aquaculture can be combined, will promote to a certain extent and strengthen bio-diversity, can also water quality be improved, promote increasing peasant income.
Adopt rice field fish culture, foster loach can increase plantation rice quality, can improve again foster loach quality of breeding fish, make aquaculture and the ingenious combination of plant husbandry, in similar environment, make rice field and fish Mutualism, improve overall efficiency.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of rice field and raises together with fish, the ecological cultivation method of loach, can form natural environment circulation, promote that paddy quality increases, the flesh of fish has natural simultaneously, safety, nutrition, delicious feature, loach can as medicinal, further raising peasant cultivation, plantation income.
Fish are raised together with in a kind of rice field, and the ecological cultivation method of loach comprises the steps:
The first step: rice field prepares
Selection Swampland reformation is rice field, and rice field periphery builds dyke, arranges annular loach ditch pool in dyke periphery, is used for breeding loach, in outlet area, rice field, dig crawl, crawl length is identical with rice field, width is less than rice field, and seed rice is selected resistant to lodging, disease-resistant strong kind.
Second step: rice field ridge process, rice field periphery arranges 80-100 centimetre of ridge.
3rd step: crawl is repaired, crawl adopts water flow waters, is in below rice field, is connected with rice field by ditch, and the draining in rice field flows in crawl, adopts polythene net to surround surrounding, prevent fish from escaping at crawl periphery.Fishpond adopts thing long simultaneously, and north and south is as well short, increases illumination further.
A kind of optimal technical scheme, in described crawl, the mode of breeding fish adopts fish culture in net pen, under the water body form of natural flowing water, net cage adopts fiber mat composition, be arranged in water body, inside and outside net cage, water constantly carries out water coke slurry in crawl, maintains the environment being applicable to fish growth in case, utilizes natural bait or artificial bait throwing in cultivate fingerling or raise marketable fish.
4th step: sterilizing in rice field, rice field disinfection, thoroughly kills virus with quicklime goods bleaching powder, eliminates parasite.
5th step: rice field transplantation of seedlings, carries out rice transplanting process rice field seedling.
6th step: absorption rice field impurity, rice field is heavy metal ion adsorbed, in order to improve rice quality, filtering ponds are set in paddy rice water inlet, paddy rice are entered water objectionable impurities and filters.
7th step: pour water to rice field, regularly to irrigation of paddy fields water, a kind of optimal technical scheme, adopts water pumper that the water in crawl is incorporated in rice field, further increases Organic Matter In Rice Fields material, realize water circulation simultaneously, using water wisely.
8th step: fertilising, implements npk fertilizer to rice field, preferred chicken manure, pig manure.
9th step: select to put fingerling in a suitable place to breed
The selection of fry, introduce physique healthy and strong, energy is strong, the carp of neat specification, silver carp, grass carp is put in a suitable place to breed, wherein breeding density, silver carp and carp respectively account for half, and grass carp puts 600 tails in a suitable place to breed at 0.07 hectare, water temperature at 10-15 degree Celsius time put in a suitable place to breed, arrange in pairs or groups according to 3 types, breeding water body space can be made full use of, the various bait of Appropriate application, accomplish to make the best use of everything, resource-sharing, plays the effect expanding the water surface.
Tenth step: put fish sterilization in a suitable place to breed
Clean 10 minutes with the saline solution of 3% before putting in a suitable place to breed, be placed on whole for the nylon sack that fry is housed in dyke
11 step: setting and the loach in loach pond are put in a suitable place to breed, the loach pond degree of depth is 1.2 meters, builds solid bottom loach pond, and abundant Polypropylence Sheet is laid in bottom, and loach escapes in control,
12 step: select Autoamtic bait putting machine to feed intake nursing to crawl, feed management, day feeding rate, forage 20-30%, fine fodder 2-4, the month that water temperature is low, within one day, feed twice, the morning forage, afternoon a fine fodder, the 7-9 month in vigorous season, within one day, feed three times, a forage, secondary fine fodder, third time between the lights.
At regular intervals, wheat bran is dropped into, dregs of beans.
13 step: the water quality of periodic adjustment loach pond and crawl, regulating water quality adopts photosynthetic bacteria culture solution, the PH numerical value of regulating water quality.
14 step: sterilize in fishpond, the lime water or use bleaching powder hanging bag of regularly splashing
15 step: prevention from suffering from the diseases, when damage by disease and insect appears in rice field, selects the pesticide control of high-efficiency low-toxicity, must guard against increasing consumption.
16 step: daily management, regularly carries out Dissolved Oxygen in Water, and the physical and chemical factor such as ph and hydrogen sulphide measures.
17 step: set aerator simultaneously in fishpond, prevent floating head.
18 step: fish and loach are fished for, after growth and maturity, fishes for fish and loach.
Beneficial effect of the present invention is: fish are raised together with in a kind of rice field, the ecological cultivation method of loach, can promote that the benignly circulated economics of rice field and fish increases, and have nursing cost low, labour intensity is low, and the rate of recapture is high, the feature that rice yield is high simultaneously.
